I saw references to a switchRGBW deviceType in the code, nice! Is it possible to use this already or is it still a work in progress?

Also, the LightScene bug I mentioned in viewtopic.php?f=3422&t=20282&start=10#p50336 is still there and it is also in BindDevices now. You might want to have a look at how the arguments are passed to the exact command in various places before releasing this code.
